Angelina gets involved in Live 8

Tomb Raider star Angelina Jolie has volunteered to be part of the Live 8 event.

The actress, also a UN ambassador, will spend the weeks in the run-up to the concerts drumming up support for the cause.

"Angelina won't just be putting her name to Live 8, she's also agreed to sacrifice a considerable amount of time for us, which is pretty much unheard of for a Hollywood star," an insider told WENN.

"She's been talking for some time about taking a break from films and we're delighted to be the ones to benefit from it."
